An amiguous address error usually means that they are looking up the
userid in some sort of directory and it matches more than one person.
 
Some systems lie and say they didn't deliver the mail when they
actually did.
 
When I delete a user because of bounce messages, I find it useful to
save a copy of a bounce message.  Then, if the user receives the
message that they were deleted and asks why, I can send them a
copy of the bounce message and they can show it to their mail
system administrator.
